Rule: prefer-on-push-component-change-detection

Enforces component’s change detection to ChangeDetectionStrategy.OnPush.

Rationale

By default Angular uses the ChangeDetectionStrategy.Default.

This strategy doesn’t assume anything about the application, therefore every time something changes in our application, as a result of various user events, timers, XHR, promises, etc., a change detection will run on all components.

By using ChangeDetectionStrategy.OnPush, Angular will only run the change detection cycle in the following cases:

• Inputs references change.
• An event originated from the component or one of its children.
• If manually called.

Notes:

Config

Not configurable.
